In reply to Alec.

Even on fairly small sites I've noticed significant differences in how the WordPress admin performs. Just so much snappier with PHP 7. It makes all the difference.

As for plugin/theme compatibility issues, this really shouldn't be much of a problem? I converted all my themes/plugins to be PHP 7 compatible months ago. I can't even remember the exact changes but the changes were trivial in my case.

Are there major technical issues in general with switching code to work with PHP 7? Perhaps for a minority, I don't know.

The way I see it is that the more people to adopt to PHP 7 NOW, the more likely it is themes/plugins still lagging behind will be updated? Otherwise where's the motivation to update code?

PHP 7 shouldn't just be for early adopters anymore (PHP 7 has been around for over 15 months now). PHP 7 is great. Everyone should benefit. I really don't think waiting another 6 months is going to change the situation much.

So on balance I'd still definitely encourage people to at least try it if their host supports it. In most cases it's just a setting in the hosting control panel so can easily be reverted.
